While his outlook is not so bad, his methods are inefficient and lead to nowhere. He wants to take power in the Likud party by democratic methods, and then being the leader of a large party run for PM.
Last Likud inner elections have shown the problem of this approach. According to the results, Feiglin should have been placed at 20th place (and because Likud won 27 mandates in the general election, he should have become a Knesset member). But he was pushed to 36th place by purely amdinistrative methods.
His chances to come to power is Likud is not much greater than those of Iranian opposition to come to power in Iran.
My opinion that he and his supporters should leave Likud and join National Union.
